I just beat my first playthrough but I noticed that I'm missing a lot of CGs/other things that I did obtain, along with some character clears. Many of the CGs I'm missing are basic ones that you automatically get throughout the story, like when Gou gives you a breakdown on enemies in the National chapter.

I did make a bunch of different saves as I played through the game. Could this be the problem?

EDIT: I can't even view the Opening Movie.

EDIT 2: Found the problem. My game just wasn't saving stuff properly. Fixed it but I'll have to redo everything in another playthrough.
